17.1%
Step-by-step explanation:
17.1%
Answer:
1. 4.13
2. 1.6933
3. 1.3013
Step-by-step explanation:
We have
Probability to be equal to 59% = 0.59
Sample size = n = 7 likely US voters
1. The mean:
= np
= Sample size x probability
= 7 x 0.59
= 4.13
2. The variance = nap
n = sample size
q = 1-probability = 1-0.59 = 0.41
P = probability = 0.59
Variance = 7x0.59x0.41
= 1.6933
3. Standard deviation
= Square root of variance
√1.6933
= 1.3013
A mean of 4.13, indicates that 4 of these voters put political correctness ahead on the average.
50 / 100 = .5
.5 is 1% of 50
.5 * 20 = 10
Does that help?

Answer:
Step-by-step explanation:
Problem 2a
The total number of ways that he can deal with his room
is 3 * 2 * 3 = 18
Problem 2b
P(green, plaid, track) = 1/3*1/2*1/3 = 1/18
Problem 2C
The bedspread and the poster don't change. The word or in probability is a real stinker. In this case it means that there are 2 choices of paint color.
The only choice that won't work is if he chooses hospital white instead of green or blue. So he has a 2/3 chance of choosing one of the two colors he wants.
The probability then becomes P(bedspread,Poster, color) = 1/2 * 1/3 * 2/3 =
2/18
